By following these guidelines, you can restore your composite decking to its original beauty and prevent long-term damage caused by bird droppings.

Now, let’s delve into the first step: preparing for the cleaning process.

Preparing for the Cleaning Process

Preparing for the cleaning process

Before you begin cleaning bird droppings off your composite decking, it’s important to gather the necessary supplies and create a safe working environment. This section will guide you through the steps required for effective preparation.

Gathering the Supplies

Cleaning supplies for composite decking

To clean bird droppings off composite decking, you’ll need the following supplies:

  1. Soft-bristle brush or sponge: Use a brush or sponge with soft bristles to avoid scratching or damaging the decking surface while ensuring effective cleaning.

Properly wetting the deck and applying a suitable cleaning solution is essential for effective removal of bird droppings. Follow these steps:

  1. Thoroughly wet the entire composite decking surface with a garden hose or pressure washer on a low setting. This helps loosen dirt, debris, and any remaining droppings.
  2. Prepare a cleaning solution by mixing a mild detergent or composite deck cleaner with water, following the manufacturer’s instructions. Avoid harsh chemicals or bleach as they can damage the composite material.
  3. Apply the cleaning solution to the affected areas, focusing on the bird droppings. Use a soft-bristle brush or deck scrub brush to gently work the solution into the deck, ensuring thorough coverage.

Scrubbing the deck

Scrubbing the deck is a critical step in removing bird poop stains and residue from the composite decking. Follow these steps:

  1. With the cleaning solution applied, use the brush to scrub the composite decking surface in a circular motion. Pay extra attention to areas with bird droppings, applying gentle pressure to remove stubborn stains.
  2. Continue scrubbing until the entire deck surface is clean and free from bird poop residue.

Rinsing the deck

  2. Pay close attention to areas previously affected by bird droppings, ensuring no residue or cleaning solution remains.
  3. Allow the deck to air dry completely before proceeding to the next steps in the cleaning process.

By following these step-by-step instructions, you can effectively clean bird poop off composite decking and restore its appearance. The next sections will cover the remaining steps to finish the cleaning process, as well as alternative methods to deal with bird droppings on composite decking.

Finishing the Cleaning Process

Finishing the cleaning process

To ensure your composite decking stays in top shape, it’s important to take a few final steps: applying a sealant and ensuring the deck is completely dry before using it again.

Applying a Sealant to Protect the Deck

Composite decking is known for its durability and low-maintenance qualities, but adding a sealant can enhance its longevity and protect it from stains, fading, and moisture damage.

Before applying the sealant, make sure your composite decking is clean and dry. Remove any remaining bird droppings or debris using the methods discussed earlier.

Choose a high-quality composite deck sealant specifically designed for use on composite materials. Look for a product that provides UV protection, water repellency, and mold/mildew resistance.

Follow the manufacturer’s instructions for application. You can use a brush, roller, or sprayer to apply the sealant. Work in small sections to ensure thorough coverage and apply an even coat.

Allow the sealant to dry completely according to the manufacturer’s recommendations, which usually takes a few hours or longer, depending on the product and weather conditions.

Keep in mind that composite decking may require resealing every few years, depending on factors such as climate, sun exposure, and foot traffic. Regularly inspect the deck for signs of wear and reapply the sealant as needed to maintain its protective properties.

Ensuring the Deck is Completely Dry Before Using

After cleaning the bird droppings off your composite decking and applying a sealant, it’s crucial to allow the deck to dry completely before using it again. This step ensures that the sealant properly cures and provides optimal protection.

To ensure the deck is completely dry, consider the following tips:

  1. Check the weather forecast: Avoid cleaning the deck or applying sealant if rain or high humidity is expected within the drying period. Moisture can interfere with the drying process and affect the effectiveness of the sealant.

  2. Allow sufficient drying time: The drying time can vary depending on weather conditions and the type of sealant used. Generally, it takes a few hours to a full day for the sealant to dry completely. Refer to the manufacturer’s guidelines for specific drying times.

  3. Ensure adequate ventilation: During the drying process, make sure the deck has proper airflow. Open windows, doors, or use fans to facilitate air circulation. This helps evaporate any residual moisture, expediting the drying time.

  4. Perform a touch test: Before using the deck, lightly touch the surface to ensure it feels dry and there’s no tackiness. Avoid walking or placing furniture on the deck until it is completely dry.

By allowing the deck to dry thoroughly, you reduce the risk of moisture-related issues and ensure the sealant’s effectiveness in protecting the composite decking from future bird droppings and other contaminants.

Remember to follow the manufacturer’s instructions for both the sealant application and drying time to achieve the best results.
